By tools and templates you mean the 'script' folder in the sdlsdk-bin zipfile right? Jimmy did point that out but it was fairly late then. We could include that in the IPy package itself from next time onwards.

Ok - thanks.

It does seem slightly confusing that to work with the latest version of
IronPython for Silverlight we need to download the sldsdk (which
includes IronPython) - and then another version of IronPython.

As they are now separate, would it make sense to offer a version of the
SDK with just the tools and templates?
